相位噪声是振荡器设计中的一个重要问题。存在几类振荡器，每一类振荡器都表现出自己的典型噪声行为。根据具体类别，存在用于优化噪声行为的各种技术。方法从振荡器本身的优化到多个振荡器的耦合而变化。两类重要的振子是一阶振子和二阶振子。一阶振荡器最有前途的优化策略之一似乎是耦合大量振荡器;然而，技术还没有完全准备好。通过耦合优化二阶振荡器似乎没有很大的通用性。在这种情况下，可以通过优化振荡器本身来实现很大的改进。
Phase noise is an important issue in oscillator design. Several classes of oscillators exist each exhibiting its own typical noise behavior. Various techniques exist for optimizing the noise behavior, depending on the specific class. Methods vary from optimization of the oscillator itself to the coupling of a number of oscillators. Two important classes of oscillators are first-order oscillators and second-order oscillators. One of the most promising optimization strategies for first-order oscillators seems to be coupling large numbers of oscillators; however, technology is not quite ready for this. Optimization of second-order oscillators by coupling does not appear to be of great general use. In this case much improvement can be achieved with optimization of the oscillator itself.
